带有angular2-mdl的FAB菜单按钮

Question

I'm building an Angular 2 app with angular2-mdl. I've add a FAB button to my page but can't find anywhere in the docs, angular2-mdl or MDL, information on how to add a FAB menu ( see image) .

Is there a way todo this with angular2-mdl or MDL? I've see it done in many apps.

Here is my button code so far:

<button (click)="editUserDialog.show()" mdl-button  mdl-button-type="fab" mdl-colored="accent" mdl-ripple>
    <mdl-icon>add</mdl-icon>
</button>

Thanks

I built a FAB menu with angular2-mdl using the popover menu from @angular2-mdl/popover and the fab-button from @angular2-mdl/core and the chip to provide tooltips.

You can check the full implementation of the fab-menu here: https://github.com/mseemann/angular2-mdl-ext/tree/master/src/components/fab-menu

The main parts of the component are the templates of the menu and of the items

for the menu:

<button mdl-button
    mdl-button-type="fab"
    mdl-colored="primary"
    (click)="fabPopover.toggle($event)"
    (touchstart)="alwaysShowTooltips = true"
>
  <mdl-icon>add</mdl-icon>
</button>
<mdl-popover #fabPopover [hide-on-click]="true" [class.direction-up]="true">
  <ng-content></ng-content>
</mdl-popover>

and for the items:

<button mdl-button mdl-button-type="mini-fab" (mouseover)="isHoovering = true" (mouseleave)="isHoovering = false" (click)="menuClick.emit()">
  <mdl-icon>{{icon}}</mdl-icon>
</button>
<mdl-chip [mdl-label]="label" [hidden]="!(fabMenu.alwaysShowTooltips || isHoovering)"></mdl-chip>

you can then use it like this:

<mdl-fab-menu #mainFabMenu>
    <mdl-fab-menu-item
        [fabMenu]="mainFabMenu"
        icon="note_add"
        label="make a note"
        (menu-clicked)="log('we need to do something here')">
    </mdl-fab-menu-item>
    <mdl-fab-menu-item
        [fabMenu]="mainFabMenu"
        icon="refresh"
        label="refresh"
        (menu-clicked)="/*do something here*/">
    </mdl-fab-menu-item>
    <mdl-fab-menu-item
        [fabMenu]="mainFabMenu"
        icon="refresh"
        label="refresh"
        (menu-clicked)="/*do something here*/">
    </mdl-fab-menu-item>
</mdl-fab-menu>
